“…The technique adopted was devel oped from that of fine-needle biopsy [14,15]. In this method, the biopsy needle is introduced free-handedly and its pro gression is shown by continuous ultrasound guidance with posterior transversal and sagittal viewing planes.…”

In the past 4 years we have carried out 650 percutaneous renal biopsies (PRB), 54 on transplanted and 596 on native kidneys. PRB was performed with a 14-gauge one-piece disposable needle that was introduced free-handedly into the lumbar wall without any form of fixed guidance or support. Ultrasound was used to locate the kidney pole and to follow the progression of the needle tip in the renal parenchyma. The time needed for the whole procedure was about 5 min. The tissue specimen was adequate for histological evaluation in 98.8% of the cases. The prevalence of post-biospy complications (haematuria, pain, anaemia) was 2.5%. Haematuria was not a common complication (1.6%) in our series, whereas clinically silent perirenal haematoma was common. Mild perirenal bleeding (volume < 5 ml) was found in 40 of a series of 150 patients (26.6%) who underwent ultrasound scan 24 h after the PRB. Haematoma exceeding 100 ml was revealed with US in only 0.6% of the patients. We conclude that free-hand ultrasound-guided PRB makes this technique easier, highly successful, time-saving and almost free of severe side effects.

“…More recently, computed tomography (CT) and ultrasonography (US) have been used in conjunction with percutaneous fine-needle biopsy for the diagnosis of both benign and malignant lesions of the pancreas, liver, retroperitoneum, spleen, and other abdominal organs [7][8][9][10][11][12][13][14][15][16][17].…”

Percutaneous fine-needle biopsy of the pancreas by real-time ultrasonography was performed in 45 patients with suspected pancreatic carcinoma. True-positive diagnoses were obtained in 27 cases, 11 examinations yielded true-negative results, 3 results were false-negative, 2 were equivocal, and 2 samples were inadequate. The overall success rate was 84.4%. No false-positive cytologic diagnoses were made. Complications were not seen in any of the patients. The results confirm the effectiveness, safety, and relatively low cost of this procedure.

“…Initially, needle placement was performed with radiographic control (Kopans and DeLuca 1980). However, with the development of high-resolution (high-frequency) transducers, US is more frequently used for guided percutaneous punctures and biopsies in even the smallest soft tissue tumors (Otto and Deyhle 1980, Reading et al 1988, Schwartz et al 1988, Matalon and Silver 1990. Preoperative localization of impalpable soft tissue tumors is attractive, because it shortens the duration of the surgical intervention and limits the extent of the excisional biopsy.…”
